MMA combines several martial arts in one discipline. That is why many MMA fighters have a background in striking, Brazilian Jiu Jitsu, grappling or wrestling. You have to be able to fight standing up, but also in the clinch and on the ground. It is precisely the switching between those distances that makes MMA so complete.
At Ruthless you can train all of these elements. You can do MMA recreationally or work towards competition and top level sport. You can start as a beginner too; by combining MMA with striking, BJJ, grappling or wrestling you build out each part further.
